Like imagine a Giselle bleeding out from their period in the wild, wouldn’t it be counterproductive to hide from predators? A lion can sniff blood from miles away so I imagine they’d have some sort of different reproductive method of expelling the uterine lining, or would they just not do it at all?

This might be slightly off topic, but what about animals that are capable of storing sperm?
I’ve read that in some reptile species, the female is capable of storing sperm for a year or more. One documentary I saw on African forest cobras, the female will store sperm after mating and will only “use it” once she finds a suitable location to lay her eggs. What triggers this?
